Androgyny is a term derived from the Greek words ανήρ (anér, meaning man) and γυνή (gyné, meaning woman)[1] that can refer to two concepts regarding the mixing of both male and female genders or having a lack of gender identification. The first is the mixing of masculine and feminine characteristics, or the balance of "anima" and "animus" in Jungianpsychoanalytic theory. The second is in describing something that is neither masculine nor feminine, for example the Hijras of India who are often described as "neither man nor woman".

To say that a culture or relationship is androgynous is to say that it lacks rigid gender roles and that the people involved display characteristics or partake in activities traditionally associated with the other gender. The term androgynous is often used to refer to a person whose look or build make determining their gender difficult but is generally not used as a synonym for actual intersexuality, transgender or two-spirit people. Occasionally, people who do not actually define themselves as androgynes adapt their physical appearance to look androgynous. This outward androgyny has been used as a fashion statement, and some of the milder forms of it (women wearing men's pants/men wearing skirts, for example) are not perceived as transgendered behavior.

Lesbians who don't define themselves as butch or femme may identify with various other labels including androgynous or andro for short. A few other examples include lipstick lesbian, tomboy, and 'tom suay' which is Thai for 'beautiful butch'. Some lesbians reject gender performativity labels altogether and resent their imposition by others. Note that androgynous and butch are often considered equivalent definitions, though less so in the butch/femme scene.

A recently-coined word, often used to refer to androgynes, is genderqueer. However, this term can be used to refer to anyone who identifies as transgender, or even someone who identifies as cisgender but whose behavior falls outside the average standard gender norms. An androgyne may be attracted to people of any gender, though many identify as pansexual or asexual. Terms such as bisexual, heterosexual, and homosexual have less meaning for androgynes who do not identify as male or female to begin with. Infrequently the words gynephilia and androphilia are used, which refer to the gender of the person someone is attracted to, and do not imply any particular gender on the part of the person who is feeling the attraction.

People who show Androgyny traits are seen in Psychology as being the most mentally stable individuals because they can see situations from both a masculine and feminine perspective. They tend to also handle social situations better than people who are typically defined as solely masculine or solely feminine. [How to reference and link to summary or text]

Intergender is also a word that androgynes can use to describe being between or beyond genders. Androgyne used to be primarily used as a synonym for hermaphrodite (a term since replaced by the word intersex), but this usage has fallen out of favor.
